Resum
On this study, periodic ultrasonic inspections were performed during flexural fatigue tests, on two different composites, and under certain conditions a confocal microscope proved useful to evaluate surface damage detected by acoustic signal analysis. Rectangular bars of plain weave glass fiber/phenolic resin composite and bars of a specific sequence of carbon fiber/epoxy resin composite were subjected to four-point bending fatigue tests until reaching 20,000 cycles, but stopping every 2,000 cyc...
